Wolfgang Lotz's Architecture in Italy, 1500-1600 is a wonderful introduction and survey of the majesty of Italian Renaissance Architecture. I had the privilage of studying under Richard Tuttle who is recognized in the introduction, who showed me the brilliance of Lotz's work as well as his ability to show the beauty of architecture. This book is a must for any serious academic student or architectural enthusiast. Lotz's presentation of Italian Architecture is a continuation of Ludwig Heydenreich's Architecture in Italy, 1400-1500, and when read together is certainly the definitive work on Renaissance Architecture. The marvelous pictures and diagrams are the best published images I have come across.

The only problem with this book is that it pre-dates recruiting publicly. So the recruiment process of contemporary western intelligence agencies are not covered. Aside from that this is a great book by a man who has an incredible life experience.
